[Ella Pearl]

Back to the ocean question though, what if she can only control true plants? I think I read somewhere that kelp isn't technically a plant, but she could control the seagrass growing around it so what if she had to make a balance while only controlling half of what she's used to?

Of course, maybe she could control anything that photosynthesizes, in which case she could make a huge algae slime monster and put the zooxa back in the coral!
